DEEP-WmL PUMP.

Application filed April 2,

T0 (17/ "fl/omit may concern.

Be it known that I. GEORGE L. FULLER, a citizen of the United States, residing at Sisquoc. in the county of Santa Barbara and State of California, have invented new and useful Improvements in Deep-\Vell Pumps, of which the following is a specificatlon.

This invention relates to oil well apparatus. and particularly to deepwell pumps for use in oil or other deep wells. At the present time it is customary in deep well pumps to provide what is known as a standing valve which may be withdrawn or seated through the medium of what is known as a Garbutt rod associated with the plunger and with the standing valve. The Garbutt rod is so formed and so inter-connected with the plunger and the standing valve as to permit the plunger to reciprocate within the limits of the pump stroke wlthout unseating the packing of the standing valve from its seat. The present invention. however. does away with the Garbutt rod, and has for one of its objects the provision of means whereby the standing valve may be seated or unseated and carried or removed to the surface of the well at the will of the operator. Another object ;is the provision of means which renders the plunger and the standing valve independent of each other during the working stroke of the plunger.

In practicing the invention I utilize some standard form,.of standing valve which is provided with a member having an annulus with two bayonet slots each separated from the other by a wall having converging edges whereby entrance to each bayonet slot is through a contracted channel serving to direct an element joined with the plunger within such channel to one leg of each bayonet slot. It will thus be seen that each member. that is. the crown portion of the standing valve and the plunger carries interlocking members. The member carried by the plunger may be the ordinary form of plunger nut provided with a rod diametrically disposed across the annular space of said nut. Obviously the plunger nut during the reciprocation of the plunger responsive to the working strokes will not engage the interlocking member on the crown portion of the standing valve. However, if the plunger nut were to so engage the interlocking member of the bottom valve the standing valve would not be unseated unless the Specification of Letters Patent.

Patented May 16,1922. 1921. 7 Serial no. 458,141.

plunger were given a sufficient twist so as to cause the rod member carried by the plunger nut to engage the vertical portions of the bayonet slots in the annulus. One edge, the horizontal edge, of each bayonet slot is under-cut in an incline above the horizontal portion of the slot or'that portion between the two vertical portions, so'that if the rod member in the plunger nut should engage the bayonet slots, the standing valve would not be removed unless suflicient twist were given the plunger. It is obvious that the under-cut portion of each bayonet slot acts as a cam to remove the rod associated with the plunger nut until a proper twist or turn is given the plunger.

The invention has for further objects the provision of a pump of the general character stated, which will be generally superior in point of relative simplicity and inexpensiveness ofconstruction combined with positiveness and effectiveness of operation, compactness in form, economy in power and freedom from frictional losses and wear and tear, and facility in'repair, and which will be generally superior in' efficiency and serviceability.

With the above 'and other objects in view, the invention consists in the novel and useful provision, construction, formation, combination, association and inter-relation of parts, members and features, all as hereinafter described, shown in the drawing, and finally pointed out in claims.

In the drawing:

Figure 1 is a central vertical sectional view of a pump constructed and organized in accordance with the invention, parts being shown in elevation and parts being broken away and sectioned for clearness of illustration;

Figure 2 is a top plan view showing one of the interlocking members associated with the standing valve member;

Figure 3 illustrates the interlocking member associated with said standing valve member. said interlocking member taken on the line 3-3. Figure 2, and resulting in unrolling said member;

Figure 4 is a fragmentary sectional View lun 'er nut used in ractic-in the invenr: P g

tion, and taken on the line 5-5 of Figure 1, looking in the direction of the appended arrows. Corresponding parts in all the figures are designated by the same reference characters. Referring with particularity to the drawing, A designates the barrel of the pump, B the plunger, C and D the means whereby the standing valve of the pum may be withdrawn with the plunger an the foot valve re-seated, and E the standing valve, all of which members are utilized in practicing one embodiment of the invention.

The means C and D-may be termed interlocking members, inasmuch as they interlock when it is desired to remove the standing Valve. The .means C includes the usual plunger nut which has a screw-threaded en- The body member 7 with its packing rings 8 is, adapted to be received within a conical shaped end piece 9. The end piece 9 is secured to the member A by means of a coupling or collar 10 having a screw-threaded engagement with the said members, as shown in Figure 1. As the pump is operated the oil or other liquid is drawn into the space above the standing valve upon the upstroke of the plunger rising above the working valve upon the. next downv stroke of the plunger, and thereafter being elevated with a column of liquid above it to produce flow at the mouth of the well.

As stated in the specification, it is necessary at times to remove the standing valve, and in order to do this the member C, constructed in accordance with the present invention, cooperates with the means D car- I ried upon the crown portion 4 of the bottom valve as shown at 11. The means d is really an annulus having two bayonet slots 12 and 13 each separated from the other by -a wall 14 having converging edges 15 'whereby entrance to each bayonet slot is figures. when the annulus is so split as toprovide a contracted channel as 16. two members as 19 and 20 are formed, and each of these members is triangularly pointed or provided with downwardl converging portions leading to the verticafslots, as shown at 21 and 22. In addition, the triangularly pointed members are provided with inclined or beveled edges, preferably beveled downward toward the channel 16, as shown at 23. The two members 19 and 20 are joined to a base member 24 which may be a flanged nut provided with a shank body. .In detail the member 24 is screw-threaded as at 25 for engagement with a correspondingly screwthreaded opening in the top of the crown member 4, as shown at 26. An annular flange 27 performs a double purpose, that of holding the member 24 in tight engagement with the member E and in addition providing a seat for the plunger nut.

eferring to Figure 1, if the plunger B were dropped the rod member 2 would engage the triangular portions of the members 19 and 20 and would likewise engage the beveled portions 23 thereof in such a manner as to rotate the plunger member B and direct the rod member 2 within the channel 16 between the two members 19 and 20. Obviously, if the rod member 2 were in direct line withthe channel 16 it would not come in contact with the members 19 and 20 and the rotation of the plunger would not be effected. The member 2 would drop to the horizontal slot of the bayonet slots 12 and I3 and. if the plunger were again lifted the rod 2 would contact with the undercut inclines 17 and would direct the rod outward and away from the means D. If it were desired, however, to 100 lift the standing valve E from its seat in the end piece 9, the plunger member would be dropped as before so that the rod 2 carried by the means C would engage the horizontal slots in the means D. A rotation of the 105 plunger B would then rotate the means C and the rod 2 would then be in a position so that upon lifting the plunger member B upwardly the rod 2 would engage the verti cal slots 18 of the bayonet slots- 12 and 13. 110 When this is done the standing valve E would be lifted from its seat.

It is obvious that a device of this character does away with the necessity of having any connection between the plunger and the 115 standing "alve. Consequently the plunger will reciprocate within given limits or may exceed those limits or may even contact with the standing valve and yet unless the properturn is given the plunger the standing valve will not be removed. I

In standard practice the standingvalve is removed or pulled out when the rods and plunger are removed, and all oil within the tubing flows back to its level. In the present invention the plunger, working valve and rods may be removed but the standing valve will still hold the oil in the tubing. Therefore there is a big saving in time and labor, inasmuch as when the plunger, work- 130 ing valve and rods are inserted back into the tubing the pump is primed and ready to produce.

It is manifest that the invention will produce a great saving in time incident to repair of pump parts and will enhance the length of life of the working parts of the pump. The various features incident to practicing the invention are simple and in expensive in construction and not liable to disengagement or to] require frequent or troublesome replacement.

It will be understood that many changes may be made in the construction, inter-re lation, formation and association of parts, members and features in the practice of the invention, and in the adaptation of the same to varying conditions of use and service,
